MACHINE FOR FLESHING 'HIDES.

SPECIFCATION forming part of Letters Patent No. 736,278, dated August11, 1903.

Application filed March 21,1903. Serial No. 148,827. (No model.)

To all whom it 'may concern.: i

Be it known that we, WALTER E. LOMBARD, a resident of Arlington, andEDWIN T. LUCE, a resident of Somerville, in the county of Middlesex andState of Massachusetts, citizens of the United States of America, haveinvented certain new and useful Improvements in Ma-Y chines for FleshingHides, of which the following is a Specification.

This invention relates to improvements in machines for removingsuperfluous i'lesh from hides, and has for its object the production ofa machine upon which hides may be fleshed with greatly-increasedefficiency and speed, while the strain upon the operator is reduced to aminimum. i y

It consists of `certain novel features and arrangement of parts, whichwill be readily un-l derstood by reference to the description of thedrawings and to the claims to be hereinafter i given.

Of the drawings, Figure 1 represents a plan view of a machine embodyingthe features of this invention. Fig. 2represen ts a right-hand end viewof same. Fig. 3 represents a central vertical section, the cutting planebeing on line 3 3 on Fig. 1. @al section of the left frame andfeed-roll-` driving mechanism, the cutting plane being` on line 44 onFig. 3. Fig. 5 represents avertical section of the right frame andknife-cylinder-driving mechanism, the cutting plane being on line 5 5 onFig. 2. Fig. 6 represents a sectional elevation of the feed-rolLcrankconnections, the cutting plane being on line 6 6 On Fig. 4. Fig. 7represents an enlarged sectional plan of the clutch mechanism, thecutting plane being on line 7 7on Fig. 5; and Fig. 3 represents asectional elevation of the same, the cutting'plane being on line 8 8 onFig.7... l

Similar characters designate `like parts throughout the several figuresof the drawings.

To support the working portion of the machine, a main frame ispreferably provided, made up of end frames 10 10 and tie-bars 1l.

. At the front or feed side a bed-roll 12, preferably provided with acovering of rubber or `machine in brackets 13.

Fig. 4 represents a .vertif like material, is mounted inthe ends of thelevers 13, pivoted at 14 to boxes 15, havinga vertical adj ustmentin theframes l0 by means of adjusting-screws 16. The lower ends of said levers13 have pivoted thereto the threaded rods 17,-having bearings at therear ofthe The rodsl7 have mounted thereon adjusting-nuts 19, between`which and said brackets 18 are interposed spiral springs 20, which tendto force said levers 13 against the adjustable stops 21, Fig.

`2, to limit the inwardmovement of the bed- .1-01112, but permit thesame to yield outwardly when cooperating with the'knife-cylinder 22,

which is mounted in a pair of arms 23, pivoted to the upper end of themachine, and is preferably provided with helical cutters. The tension ofthe springs 20 may be regulated by adjusting the nuts 19 on the rods 17.At the pivot of said arms 23 is located a shaft 24,

.having securedto one end a gear 25 and a pulley `26, while `on theother end is secured apinion 27.

Intermediate of the side frames 10 a driving-pulley 28 (shown only inFig. 5) is mounted upon said shaft 24 to drive the same. The gear 25meshes with an intermediate gear 29, mounted on one of the arms 23,which in turn meshes with a gear 30, on a hub of which is mounted a gear3l, which meshes with a gear 32, secured to the knife-cylinder trunnion33 for the purpose of revolving the knife-cylinder at a high rate ofspeed. To the frames 10 at 34 are pivoted a pair of arms 35, in theupper ends of which is mounted a feed-roll 36, preferably corrugated, onthe left trunnion 37 of which is mounted a radius-arm 38, pivoted at 39to a second radius-arm 40, the other end of which is pivoted to thedrivingshaft- 24.

A gear 4l is mounted on the pivot 39 ofthe radius-arms 38 40 and meshesWithand is driven by the gear 27 on the driving-shaft 24, which motionis transmitted toa gear 42 on the shaft 37 for the purpose of revolvingthe feed-roll 36 and causing the hides to be fed when said roll is inposition tocoact with the bed-roll 12.

At 43 are pivoted levers 44, having mounted sov ` a gear 51 and on theother end a crank 52,

each being provided with a crank-pin 53, which is connected by a link 54'to a knifecylinder arm 23. A half-revolution of the crank 52 will causethe knife-cylinder to be moved toward the bed-roll 12, and thecompletion of the revolution of said crank 52 will cause saidknife-cylinder to be moved away from said bed-roll into itsnon-operating position.

The crank-pins 53 are also provided with a bearing 55 for the free endsof the rods 56, pivoted to the feed-roll arms 35. The rods 56 passfreely through bearings 55 and are provided at their inner ends withnuts 57, which limit the movement of said arms 35 toward thehide-supporting rolls. The limitation of this movement may be varied byan adjustment of thenuts 57. About said rods 56 are coiled spiralsprings 58 betweensaid bearings 55 and nuts 59, adjustable on said rods56, thereby permitting the feed-roll to yield when coacting with thehide-supporting rolls 45 and 12. The gear 51 meshes with a gear 60,mountedupon a shaft 61, having an enlarged portion 62 and mounted inbearings 63. Upon the enlarged portion 62 is mounted a pulleyT 64,connected by a belt 65 to the pnlley-26on the shaft 24, by which motionis transmitted to said pulley 64 to cause it to continually revolvewhile the machine is in use. l

The enlarged portion 62 is provided with a locking-bolt 66, whichprojects beneath the inner periphery of said pulley 64 and is flattenedat this point, so that in its normal position the flattened portion ofsaid bolt conforms to the periphery of a hub 62* of the enlarged portion62 and permits of a free movement of said pulley 64 about the same. Oneend of said bolt 66 is provided with an arm 67, which is presseddownward by a spring 68 to cause said locking-bolt 66 to turn in itsbearing, so that it will engage notches 69 on the inner periphery ofsaid pulley 64 and cause the revolution thereof to be transmitted to theshaft 61 and the gear 60, thereby transmitting motion to the gear 5l andcausing a half-revolution of the cranks 51 52.

To prevent the shaft 6l from being revolved by the pulley 64 until it isdesired to operate upon a hide, a stop-pawl 70 is provided, pivoted toone of the frames 10 at 71 and connected by a link 72 to a lever 73,mounted upon a short shaft 74 in one of the frames 10 and provided atits opposite end with a lever 75, connected by a spring 76 to astationary part, and also provided with a lug 77, with which the hook 78on the upper end of a rod 79 coacts, said rod 79 being connected to atreadle 80, pivoted at 81 to the rear of the machine. A spring 82connects said rod 79 to a stationary part, thereby keeping it in aposition to coact with the lug 77 when the treadle 8O is operated, astrap 83 limiting the movement of the upper end of said rod 79 in eitherdirection. A brake 84, coacting with the enlarged portion 62, retardsthe shaft 61 as it completes a revolution.

The operation ofthe machine is as follows: The various partsvof themechanism being in the position shown in the drawings, a hide is takenby the operator and thrown over the upper hide-supporting roll 45, sothat its center is somewhat below the bed-roll 12. The operator thenplaces his foot upon the treadle, depressing the same, which causes thehook 7S to engage the lug 77, thereby rocking the shaft 74, and throughthe lever 73 'and link 72 the stop-pawl70 is removed from beneath thearm 67 on the locking-bolt 66. The spring 68 is then free to move saidbolt about its axis, causing a shoulder of its flattened portion toproject beyond the periphery of the reduced hub 62* and engage With anotch 69 of the pulley 64, thereby causing motion to be transmitted fromthe drivingshaft to the shaft 61 and the gear 60, mounted thereon. Assoon as the'hook 7S has acted upon the lug 77 it passes the same andpermits the spring 76 to move the pawl 70 into its normal position, sothat when the shaft 61 has made a complete revolution the arm 67 willcome into contact with said stop-pawl 70, forcing the locking-bolt 66out of engagement with the notches in said pulley and back into itsnormal position,with its attened portion conforming to the periphery ofthe enlarged portion 62, thereby preventing a further revolution of saidshaft 6l and gear 60 and permitting the pulley 64 to freely revolve. Thegears 51 and 60 are tWo to one, so that a complete revolution of thegear 60 Will cause a half-revolution of the gear 51, so that when theoperator presses his foot upon the treadle he thereby causes ahalf-revolution of the gear 51 and the crank 52, thereby forcing theknife-cylinder into cooperating position with the bed-roll 12 and thefeed-roll 36 into a position between the hide-supporting rolls 45 and12. When the feed-roll 36 is moved into position to coaet with thehide-supporting rolls,it wraps the hide about nearly onehalf thecircumference of the former, thereby giving it sufficient surface ofcontact to feed upward the slippery material. The knifecylinder throughits gearing is being continually revolved While the feed-roll 37 is alsobeing continually revolved, so that as soon as the cranks have movedsaid knifecylinder and said feed-roll into position to Operate thefeed-roll immediately impinges IIO 'maeva upon the hide and causes it tobe fed over the supporting-rolls, while at the same time thefleshing-cylinder immediately upon reaching its operating positioncommences to remove the superfluous iiesh from the hide as it is p fedbeneath, its helical form at the same time keeping the hide smoothlystretched. When one side of the hide has been fleshed, the operatordepresses the treadle 80 a second time, causing the pawl 70 to betripped again to permit a second complete revolution of the shaft 6l,thereby causing the crank 52 to make another halfrevolution to move theknife-cylinder and feed-roll into their nonoperating position,in whichposition they will be locked until the tread'le `SO is again depressed,when the operation may be repeated. The hide is then reversed and isagain placed upon the hide-supporting rolls, and the unieshed portion issubjected to the action of the knife-cylinder. r

By-the providing `of the clutch mechanism to move the knife-cylinder andfeed-roll into position to act upon the hides all the strain upon theoperator is removed and the power necessary to do the work of i'leshing:is derived from a mechanical source, which is a greatimprovementin theart of ieshing hides. The mounting of the hide-supporting rolls and 12in the ends of the pivoted levers controlled by springs is also animportant feature of this invention, inasmuch as when the feed-roll ismoved into position to'coperate with the same and they are obliged toyield in order to permit inequalities in the hides to freely pass thesupporting-rolls are more sensitive to such inequalities, being on theends of pivoted levers, than would bethe case when the feed-roll wouldhave forced them to yield by a direct thrust. It is obvious that while acrank-pin 53 is shown this pin might be venlarged to the size of aneccentric without altering the principles of this invention.

By the use of this improved machine the operator may handle the hidesthroughout the treatment withbut slight change in po- `sition of thebody.

Having thus described our invention, we claim-` r l. Thecombinationwithapairofseparated supporting-rolls, of a feed-roll movable towardandfrom a position between said supportingrolls, a pair of pivoted arms,and a knife-cylinder mounted in the free ends of said arms and whollysupported thereby,
